The surface of the RumbleRoller contains specially designed bumps that are firm, but flexible, much like the thumbs of a massage therapist.
As you roll over the top of the RumbleRoller, the bumps continuously knead the contours of your body, gently stretching soft tissue (muscle and fascia) in multiple directions. This action erodes trigger points, helps restore flexibility, and brings quick relief to common types of muscular pain. By design, the RumbleRoller's bumps are firmer than muscle tissue, but much softer than bone, so they deflect out of the way if they contact your spine or other bony protrusions.
Through simple techniques, you can control the amount of pressure the bumps apply to your body. The bumps are closely spaced to one another (< 2" apart), so several of them simultaneously contact your body during most exercises. However, with a slight shift of your body, you can reduce your area of contact with the RumbleRoller, which increases pressure and provides deeper, more penetrating relief.
The RumbleRoller is made in two different sizes, and each size is available in two different densities. The information below will help you choose the best model for your particular needs.
RumbleRoller models, clockwise from left:
Full-Size or Compact
If you plan to use your RumbleRoller in a single location -- e.g. at home -- you'll love the full-size model, because its extra length makes it more efficient for performing many exercises. It's long enough to roll the widest part of your back in one pass; you can roll both legs (quads, hamstrings, and/or calves) at the same time; and you can even transition from one IT band to the other without moving the roller. With the Compact RumbleRoller, you'll need to roll each leg separately, and will spend a little more time repositioning yourself between exercises.
The major advantage the Compact RumbleRoller has over the full-size model is its portability. At just 12" in length, it fits easily in your gym bag, backpack, or carry-on luggage. This makes it a favorite of runners and triathletes, who transport theirs from race to race. The Compact RumbleRoller's smaller diameter (5" vs. 6" for the full-size model) allows it to conform better to the curvature of some body parts, such as your neck. The Compact RumbleRoller also costs less than the full-size model, which may be important if your budget is limited.
Original Density or Extra-Firm
If you're new to foam rolling or have gotten positive results from any type of conventional foam roller, you'll want the original density (blue). Even though this is our "softest" roller, it's still more aggressive than any other foam roller on the market. The extra-firm version (black) is intended for experienced users with especially dense muscle tissue that doesn't respond to normal massage pressure.
The RumbleRoller's massaging action can be further intensified by changing your movement from a back-and-forth rolling motion to a side-to-side rocking motion. That's because the RumbleRoller's bumps have an asymmetrical shape that allows them to flex more easily in one direction. During rolling movements (i.e. the most common roller exercises, with the roller moving beneath you), the bumps flex relatively easily, and provide a wiping-type massage pressure. However, if you rock from side-to-side toward the RumbleRoller's ends, the bumps are forced to flex in a direction in which they're designed to be somewhat stiffer. This creates a deeper "digging" pressure.
This rocking technique nearly doubles the number of ways you can use a foam roller. It's especially effective for penetrating dense tissue like that of your calves, as well as hard-to-roll areas like your upper lats and even your neck.
Before creating the RumbleRoller, they spent years studying other foam rollers, and testing many different types of advanced polymers. Their material research resulted in a product that has several times the strength and tear resistance of conventional rollers, has a wonderful feel, permanently retains its shape, and is guaranteed to outlast and outperform any foam roller that you've ever used.
The RumbleRoller's smooth, nonporous surface repels most dirt. It's also water-proof and latex free, and includes a molded-in antimicrobial additive that helps prevent the growth of bacteria and fungus. To clean your RumbleRoller, simply wipe it down as needed with soap and water or any common household cleaner.
